【摘要】 在合理布置的情况下,双文丘利和机翼这两种测风装置都可以满足锅炉机组对风量测量的控制要求。但在实际运行中,有一些机组的测风装置布置不尽合理,至使风量测量偏差过大或完全不能使用,锅炉通风量难以准确调整,影响锅炉机组的燃烧和控制。根据双文丘利在电厂应用中存在的问题,提出了改进办法,取得了较好的效果,具有一定的借鉴推广价值。更多还原

【Abstract】 The Double-Venturi wind-measuring device and aerofoil can meet the air quantity controlling require ments of the boiler under the reasonable collocation.But during the actual operation,the windage is so larege or can’t be used at all resulting from irrational arrangement of wind-measuring device that the ventilation is difficult to adjust and this affects the boiler’s combustion and controlling.This article puts forward the improvement way on the basis of the application of Double-Venturi wind-measuring device in thermal power plant and gets a better effect which can be tak en as reference.更多还原
